SECTIONAL COUPLING JOINT FOB AUTOMOBILE BADIATOBS.

Application filed April 22, 1 922. Serial No. 556,064.

To all whom t may camera.'

Be it known that I, ALBERT BERMAN, a citizen of the United States, residing at Brooklyn in the county of Kings and State of New York, have invented certain new and useful 1m rovements in Sectional Coupling Joints fidi' Automobile Radiators,of which the following is a specication.

My invention relates to a sectional coupling joint, 'particularly applicable for use with individual units of a sectional automobile radiator, to removably secure such units to the water manifold chambers of the radiator tank and to provide suitable inlet' and outlet passages `between the manifolds and the separate units whereby water may circulate freely between the elements without danger of leakage at the joints.

In the construction of sectional radiators it is customary to provide projecting ears at opposite ends of the individual units, each ear having a central water passage and bolt receiving openings at opposite sides of the passage. It has been attempted to form a water tigt joint between the sections and the tank of the radiator by the use of other packing means between the ears and the water manifold; but, so far as I am aware, this expedient has failed of its purpose, due probably to the difficulty of obtaining ual pressure against the packing. at all lnts about the passages, inasmuch as the c amping action of the bolts is effective only at two'fairly widely separated points about the assa e. At parts remote from the bolts eakage is likely to occur. The present invention therefore contemplates the provision of a single opening in both the unit and the manifold, which are separated by a gasket, and which are removably. secured together through openings by means of a sectional coupling joint of the character hereinafter described, and it is the primary object of the invent-ion toprofvide a sectional coupling joint which will effectively hold the individual sections in their respective relation to the radiator tank without danger of leakage, and at the same time permit free circulation vof the water through the couplin: joint into and out of the separate radiator unita The invention is fully described in the following specification and set forth in the appended claims, and illustratively exempli ed in the accompanyingdrawings, in vwhich Figure 1 is a front elevational view of a radiator tank showing the individual sections in their respective positions and one section omitted; Figure 2 is a substantially transverse sectional view of the upper portion of a radiator section, water manifold, and coupling joint for detachably connecting` the-two elements together; Figure?) is a perspective view of the sectional coupling joint; and Figure 4 is a perspective view of a portion of a sectional radiator unit showing parts `broken away to show the lconstruction of the water passages and one member of the sectional coupling.

Referring to the drawings, and particularly to the construction of the radiator tank shown in Figures 1 and 2, 10 denotes the permanent radiator tank comprising upper and lower members, both members being provided with manifold chambers 11. The upper and lower members 10 are rigidly supported at their ends andspaced apart from each other by side irons 12, which constitute the side walls of the radiator proper. The manifold chambers 11 extend substantially the entire width of the upper and lower members 10 between the side irons 12, and are disposed on a plane substantially rearward of the face of the radiator itself, so that a. shoulder or seat is provided against which the individual sections are seated. The manifold chambers 11 are rovided with a. plurality of openings 13 in t eir forward walls through which communication is established between the tank and a series of individual units 14.

The units 14 are assembled in relation to the permanent tank 10 in the manner shown in Figure 1, i. e., side by side, so that water from the tank 10 circulates in a vertical direction andl in separate units deiined by the sections themselves. The sections comprise upperA and lower auxiliary tanks 15 and communicating with both thereof is a plurality of series of tubes 16 arranged tween honey comb or any other suitable grid construction 17. The auxiliary tanks 15 are each provided with/a singlel central opening 18 in the rear wallthereof, the said opening .being adapted to register with one of the nlngs 13 in the manifold chambers 11. gasket 19 having a central opening in Figure 2. Inl

be-loo order to reenforcefthe opposite walls of the auxiliary tanks 15 against external pressure I have provided a conically shaped cage 20, forming one unit of the sectional coupling, Vand having an annular flat base portion 21, ladapted to ree-nforce the marginal portion of the material surrounding the opening 18. The opposite end of the cage 20 is formed by a strap portion 22 having its ends integral with the annular portion 21, the outstanding portions of the strap 22 being inclined toward the axis of the cage 2O and terminating in a transveise end seci tion 23. The section 23 is provided with an opening 24 axially aligned with the opening in the base'portion 21. It Will be noted;

with reference to Figure 2, that the V'cage 20 is substantially the Width of the inside dimension of the auxiliary tank 15 and in the course of manufacture it is desirable to se- YVcure together'the adjacent surfaces of the cage 20.

In order to detachably secure the sections 14: in position with relation to the permanent tank 10 and at the upper and lower ends thereof, coupling joints 26 forming lthe other element of the sectional couplings are mounted in the manifold chambers 11 of the tank 10 at the opening 13. Each coupling comprises a cage having a. frustro conical body portion 27 provided with an annular flat bearing surface 28 at its base adapted to bear against and to be secured 'to the inner surface of the forward wall of the chamber 11. 7The forward side of the portion 28 is provided with an integral cylindrical section 29 which projects through the registered openings 13 and 18, and extends well into 'the auxiliary tank 15 after b projecting through the opening in the portion 21 of the cage 20. The diameter of the cylindrical section 29 is such as to lit closely the openings 13 and 18. The cylindrical section is virtually a she-ll having a through bore 30 axially aligned with the axis of the openings 13, 18 and -25 and is adapted to esa.blish communication between the manifold-'chamber 11 and the auxiliary tank. 15. The conical portion of the body 27 is provided with a transverse through openin 31 communicating at opposite ends 'with to interior of the inamfold cham- Ygreniers? ber 11 and receiving the inner terminus, of bore 30, at its midportion.. The reduced end of the body 27 terminates. in an axially bored nipple 82, the bore of which is threaded and axially aligned with the coupling joint 26. In order to drawV the auxiliary tank 15 tightly against its seat in the manifold chamber 11`and to force the adjacent faces of the elements into closer relation with each other and to compress the gasket 19 therebetween, a bolt 33 is inserted through'the openings 24 and 25 in the front wall of the tank 15 and adjacent portion of the strap 22, and its threaded end screwed into the threaded bore of the nipple 32. As the bolt 33 is tightened 'the head portion will seat against a washer 34 ydisposed between the head portion and the face of the tank 15, as illustrated in Figure 2. lt will be apparent that by tightening the bolt 33, the reenforced peripheral marginal face of the auxiliary 'tank [15 will be forced a ainst the gasket 19 supported against the similar reenforced marginal portion of the manifold chamber 11, thereby forming a substantially water tight joint between the permanent tank 10 and vthe section 1d.

The operation of removing and replacing a section is as follows z-Assuming that the portion of the section 141 shown in Figui-e2 is to be removed from the permanent tank 10, the bolt 33 is unscrewed from the nipple 32 by rotating the head of the bolt by means of a wrench or other: tool. After removing both the upper and lower bolts in this manner the section 1li may be drawn forwardly and detached from the manifold chambers 11 and permanent tank 10. To replace the parts position the section 14 so thrt the openings 18 will register with the opening 13 and then screw the bolts 33 into the nipplesj32 until the auxiliary tanks 15 at .each end of the section "i4 are seated against the gaskets 19 and manifold charnbers 11.y

With the particular construction above described it will vbe apparent that an unobstructed passage is maintained through the sectional coupling from the manifold chamber 11 to the interior of the adjacent auxiliary tank 15 and section 14. lt will also e apparent that due to the axial pull resulting from tightening the bolt 33 with respect to the coupling joint 26, the pressure against the gasket. 19 will be evenly distributed Whereby the joint is substantially sealed against possible leakage.

Having fully described my inventionv what I claim and desire to secure by Letters Patent is 1. The combination with a tankY and se arable radiator unit, of a couplin of t e character described, comprising a justable sections disposed at o posits sides of adje/- cent walls of the and radiator unit,

lll)

-said seeftiiis comprising annuiar members the tank and the radiator unit` one of said members being provided with a Hange adapted to telescope Within the opening in the other member, and means for adjust-ing said sections relative-1y of each other to bring the adiaeent Walls of the tank and radiator unit together to form a joint, said straps being provided with aligned openings to receive the said means.

2. The combination of elements as claimed in claim 1, in which one of said members is adapted to be disposed between opposite walls of the tank and Whose strap has a transverse end portlon provided with an openlng, and in which `the other members strap pro- "jects into the radiator and has a threaded bore at the end thereof, the said means rfor adjusting the said sections comprising a bolt the head of which is seated against the tank Wall adjacent the opening in the first strap vand the stem portion thereof being disposed through the openings and adapted to be engaged by the threads of the opening in the 'second strap, substantially as described.
